Total natural gas consumption in 2021 reached 378.5 TWh, 5% higher than in 2020, driven mainly by a recovery in economic activity.
Conventional demand, for household, commercial and industrial consumption, which represents around 76% of the total demand, grew by 6% compared to the previous year, reaching 288 TWh. This increase has been motivated by the recovery of the economic activity, which has led to greater industrial demand, as well as due to colder temperatures at the beginning of the year.
Demand for the generation of electricity has also seen a 2% growth compared to 2020, to reach 90 TWh, mainly due to a lower contribution from hydro and nuclear production.
Security of supply
On the supply side, in an environment of high volatility in international energy markets and thanks to the anticipatory measures adopted, such as the allocation of additional slots at Spanish regasification plants, the Spanish Gas System has higher average levels of contracted natural gas capacity than in previous winters on the same date.
In 2021, the Spanish Gas System operated normally and with 100% availability 24 hours a day, every day of the year.
Note: These data are provisional, pending final year-end.
